FIELD: transport engineering.
SUBSTANCE: invention can be used in transmissions of wheeled vehicles. Proposed transfer case with power takeoff unit has housing 1, drive shaft 5, countershaft 10, power takeoff shaft 17 and divider 25. Divider 25 is connected with lubricating pump 23 and gear 19 fitted on power takeoff shaft. Divider 25 is installed coaxially with drive shaft 5 between drive shaft and power takeoff shaft 17. Divider 25 is made in form of two rings getting one into the other with clearance. First ring is fixed in housing 15 of power takeoff unit and second ring is fitted on end of driven shaft 5. Grooves are made on outer and inner surfaces of rings interconnected by channels. Drive shaft 5 has groove and axial channel 13 connected with ring groove by radial channel. Channel to deliver lubricant from lubricating pump 23 to first ring of divider is made in housing 15.
EFFECT: improved reliability and increased service life owing to provision of lubrication of bearings of drive shaft and power takeoff shaft.
